Content for third class

The child should be enabled to

  • Estimate, compare, measure and record lengths of a wide variety of objects using appropriate metric units (m, cm) such as everyday objects, furniture, heights of children etc?
    Estimate length and height without and with unit of measurement present measure to check estimates?
  • Rename units of length in m and cm - 125 cm = 1 m 25 cm
  • Solve and complete practical tasks and problems involving the addition and subtraction of units of length (m, cm).
    Confine to totals that can be readily checked by measuring.

Content for fourth class

  • Estimate, compare, measure and record lengths of a wide variety of objects, using appropriate metric units, and selecting suitable instruments of measurement such as lengths and heights of doors, corridors, school yard, paths, drives, playing-fields using instruments like rulers, tape measures and trundle wheels?
  • Rename units of length using decimal or fraction form e.g.
    25 cm = 0.25 m = quarter m
    2 km 150 m = 2150 m = 2.15 km
  • Understand, estimate and measure the perimeter of regular 2-D shapes
  • Solve and complete practical tasks and problems involving the addition, subtraction, multiplication and simple division of units of length (m, cm, and km).
